Constructs a method entry

Parameters:

modifiers - access permission to and properties of the method

name - the simple name of the method (or

init

or

clinit

)

type - the method signature

exceptions - the checked exceptions the method may throw

code - the virtual machine instructions and auxiliary infos

deprecated - is this method deprecated ?

synthetic - is this method synthesized by the compiler ? NOTE: VMS 4.7.4: There must be exactly one Exceptions attribute in each method_info structure.

MethodInfo
